Abstract: We report on searches for B s 0 → μ + μ − , B d 0 → μ + μ − decays and b → s μ + μ − transitions in exclusive decays of B mesons. Using 2 fb -1 of data collected by the CDF II detector we find upper limits on the branching fractions B( B d 0 μ + μ − ) < 5.8 → 10 -8 and B( B d 0 → μ + μ − ) < 1.8 → 10- 8 at 95% confidence level. Using 924 pb -1 of data we measure the branching fractions B( B + → μ + μ − K + ) = (0.60 ± 0.15 ± 0.04) × 10 -6 , B( B d 0 → μ + μ − K *0 ) = (0.82 ±0.31 ±0.10) × 10 -6 and the limit B( B s 0 → μ + μ − ϕ)/B( B s 0 → J /ψϕ) < 2.61(2.30) × 10 -3 at 95(90)% confidence level.
